Title: Method and apparatus for controlling load of ac generator applied to engine
Inventor: RUISU TEII YOSHIDA
IPC: F02D41/30
Filed: 1988-07-16
Abstract: PURPOSE: To enhance efficiency of an engine by reducing or stopping the power generating operation of an AC dynamo when the loading state of the engine is detected and a heavy load is being applied to the engine. CONSTITUTION: A load control system 10 detects both of the vacuum (this indicates the load of an engine) of a manifold from an engine E and the voltage of a battery. Also, the load control system 10 controls a solid state switch 40 to energize the field winding F of an AC generator A or perform energy absorption, thereby enabling or disabling the charging system of the AC generator A. When a heavy load is applied to the engine, the charging system of the AC generator is disabled, and when the load of the engine is light or when idling operation is being performed, the charging system is enabled.

Title: Automatic pump type thrust bearing for vertical spindle rotary electrodynamic machine
Inventor: HANSUYURUGEN POROTSUKU
IPC: F16C37/00
Filed: 1982-10-08
Abstract: A self-pumping thrust bearing for electric machines having a vertical shaft is disclosed in which oil circulates through radially-extending bores in a rotating thrust ring to suck hot oil from an oil space and transfer it to a ring canal disposed in a stationary part. In order to make the transition from the rotating thrust ring to the stationary ring canal as loss free as possible, there is arranged on the outside at the thrust ring a circular canal into which the bores lead. This circular canal is bounded on the side facing the stationary part by a height-adjustable ring which is held at the thrust ring with a gap between the ring and the thrust ring. The transfer of oil therefore takes place around the entire circumference of the thrust ring so that turbulence is avoided. The quantity of oil pumped can be adjusted by adjusting the width of the gap.
